IE has lots of version(IE 6\7\8\9\10\11\Edge)
We usually test the page compatiblity in different IE version. But Microsoft does not allow multiple versions of IE coexist in a PC. I have to use 3 PC for testing in IE9\10\11 at least.
Superpreview for IE is a excellent IE compatiblity test tool. But it has already no technical support from Microsoft. Our site needs to log in first , then display a flash figure. The Superpreview doesn't work correctly.
Here's the question:
Does anyone has other better test tools for page compatiblity in different IE version?
